Member Function Documentation

H5T_order_t H5::AtomType::getOrder (   )  const

Returns the byte order of an atomic datatype. Returns: Byte order, which can be: H5T_ORDER_LE H5T_ORDER_BE H5T_ORDER_VAX Exceptions: H5::DataTypeIException

H5T_order_t H5::AtomType::getOrder (  string &  order_string  )  const

This is an overloaded member function, provided for convenience. It takes a reference to a std::string for the buffer that provide the text description of the returned byte order. The text description can be either of the following: "Little endian byte ordering (0)"; "Big endian byte ordering (1)"; "VAX mixed byte ordering (2)";. Parameters: order_string  - OUT: Text description of the returned byte order Returns: Byte order, which can be: H5T_ORDER_LE H5T_ORDER_BE H5T_ORDER_VAX Exceptions: H5::DataTypeIException

void H5::AtomType::setOrder (  H5T_order_t  order  )  const

Sets the byte ordering of an atomic datatype. Parameters: order  - IN: Byte ordering constant, which can be: H5T_ORDER_LE H5T_ORDER_BE H5T_ORDER_VAX Exceptions: H5::DataTypeIException

int H5::AtomType::getOffset (   )  const

Retrieves the bit offset of the first significant bit. Returns: Offset value Exceptions: H5::DataTypeIException  Description For information, please see C layer Reference Manuat at: http://hdf.ncsa.uiuc.edu/HDF5/doc/RM_H5T.html#Datatype-GetOffset

void H5::AtomType::setOffset (  size_t  offset  )  const

Sets the bit offset of the first significant bit. Parameters: offset  - IN: Offset of first significant bit Exceptions: H5::DataTypeIException  Description For information, please see C layer Reference Manuat at: http://hdf.ncsa.uiuc.edu/HDF5/doc/RM_H5T.html#Datatype-SetOffset

void H5::AtomType::getPad (  H5T_pad_t &  lsb, H5T_pad_t &  msb )  const

Retrieves the padding type of the least and most-significant bit padding. Parameters: lsb  - OUT: Least-significant bit padding type msb  - OUT: Most-significant bit padding type Exceptions: H5::DataTypeIException  Description Possible values for lsb and msb include: H5T_PAD_ZERO (0) - Set background to zeros. H5T_PAD_ONE (1) - Set background to ones. H5T_PAD_BACKGROUND (2) - Leave background alone.

void H5::AtomType::setPad (  H5T_pad_t  lsb, H5T_pad_t  msb )  const

Sets the least and most-significant bits padding types. Parameters: lsb  - IN: Least-significant bit padding type msb  - IN: Most-significant bit padding type Exceptions: H5::DataTypeIException  Description Valid values for lsb and msb include: H5T_PAD_ZERO (0) - Set background to zeros. H5T_PAD_ONE (1) - Set background to ones. H5T_PAD_BACKGROUND (2) - Leave background alone.

size_t H5::AtomType::getPrecision (   )  const

Returns the precision of an atomic datatype. Returns: Number of significant bits Exceptions: H5::DataTypeIException  Description The precision is the number of significant bits which, unless padding is present, is 8 times larger than the value returned by DataType::getSize().

void H5::AtomType::setPrecision (  size_t  precision  )  const

Sets the precision of an atomic datatype. Parameters: precision  - IN: Number of bits of precision Exceptions: H5::DataTypeIException  Description For information, please see C layer Reference Manuat at: http://hdf.ncsa.uiuc.edu/HDF5/doc/RM_H5T.html#Datatype-SetPrecision

void H5::AtomType::setSize (  size_t  size  )  const

Sets the total size for an atomic datatype. Parameters: size  - IN: Size to set Exceptions: H5::DataTypeIException

virtual string H5::AtomType::fromClass (   )  const [inline, virtual]

Reimplemented from H5::DataType. Reimplemented in H5::FloatType, H5::IntType, H5::PredType, and H5::StrType.
